Infrared detectors are finding new applications and facing new challenges.Hank Hogan, Contributing EditorWhere vision ends, infrared begins. Stretching from 0.7 to 1000 μm, the infrared spectrum covers a lot of ground, as do the imaging applications that make use of this part of the spectrum. These applications include biological studies, surveillance, fusion research and thermal imaging that...Read full articleRelated content from Photonics MediaARTICLESStealth Sheet Conceals Hot Objects from IRAn ultrathin cloaking material has been developed that can hide hot objects, such as human bodies and military vehicles, from IR cameras.

It performs single-ended tests and can calculate fiber attenuation and uniformity and splice and connector losses. It can also locate breaks and determine fiber length. Its ability to locate and measure reflectance and loss makes it the troubleshooting and fault locating equipment of choice. New generation OTDRs include advanced functions such as macrobend location, active-fiber testing and automatic trace acquisition.An optical time-domain reflectometer sends short pulses of light into a fiber and measures its reflections as a function of time. The delay of these reflections to the detector as well as their...Photonics HandbookConnectors and Splices: Correct Alignment Spells Success: Whether the job is splicing fibers together or connecting fibers to system devices, alignment is the key to success. This article explores the many ways to achieve that goal.Just as an electronic connector provides a pluggable connection between electronic circuits, a fiber optic connector provides an optical one. The goal is joining a fiber to a transmitter, receiver or...Photonics HandbookPhotomultipliers: Low-Light, High-Speed Specialists: Rapid detection of light calls for a sensitive detector and electronics that do not introduce additional signal noise. In fact, for very rapid detection, detector shot noise does not determine the signal-to-noise ratio. Instead, the amplifier has the most impact, which is why many designers have selected a photomultiplier tube for the high-speed or low-light-level detection of photons.The applications where rapid detection of light is a must are many. They include a wide variety: semiconductor inspection, gene sequencing, oil well logging and high-energy physics. The reasons for...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookWHITEPAPERSHow Infrared Cameras Capture Beyond the InvisibleInfrared cameras, also known as thermographic cameras, differ from cameras that capture images within the visible spectrum.
